Surge arrester for use in e.g. photovoltaic system, has link type clamp arranged in movement path of conductor section or link and comprising end coming in contact with link when switch guide is activated

摘要

The arrester has a switch guide (3) comprising a solder joint connected in an electrical connecting path within a varistor. A moving conductor section or a moving conductive link is connected with the varistor via the solder joint. A link- type clamp (17) is arranged in a movement path of the conductor section or the conductive link. The clamp has an end coming in contact with the link when the switch guide is activated, and another end is connected to an electrical external connection of the varistor. A protection unit protects contact points between the link and the link-type clamp.
